(a) would give you the option of reporting the LR statistics for each
coefficient, just like SPSS will let you do now. (I imagine this would be
a fairly simple ado file? Has somebody maybe done it already?)

As usual, Stata and its users are ahead of me; see Zhiqiang Wang's
-lrdrop1- routine. However, I don't see anything yet that works like the
LrTest alternative I describe below.

(b) had an LrTest command that didn't require you to first estimate the
constrained model yourself; it would just do it for you.
